A range war is a type of armed conflict that occurs in agrarian or stock-rearing societies. The subject of these conflicts was control of "open range", or range land freely used for cattle grazing, which gave the conflict its name. Typically they were disputes over water rights or grazing rights.

^For example, from the Santa Clarita Valley Historical Society site CECILIA RASMUSSEN. "Castaic Range War Left Up to 21 Dead". Santa Clarita Valley Historical Society. Retrieved 2004-07-04. (sourced from the Los Angeles Times): "The violent, long-running Jenkins-Chormicle feud, which started in 1890 over a boundary dispute, is a colorful and cruel saga — part fact, part myth — of barn burnings, ambushes and gun battles on horseback. It lasted more than two decades." describes a Southern California range war that started in 1890.

^For example, from the U of Idaho Range Management site telling of conflict in Idaho: " Range wars continue, just as they did a century ago, between those who have grazing rights and those who do not. Today these range wars pit ranchers, with state grazing leases, against the environmental groups that are trying to restore the grazing lease areas to a healthy and pristine land. The weapons have changed from the cold steel of a gun to the amount of cold hard cash a rancher or an environmental group will pay for a piece of land."

^For example, from the MSNBC site, telling of Bureau of Land Management policy changes and impacts: "The mustangs' current troubles come thanks in part to another Western icon: cattle ranchers. There are currently 37,000 mustangs sharing public rangelands with several million head of cattle. The result has been overgrazing, exacerbated by six years of drought. To restore the land, the BLM has cut the number of cattle allowed, and ranchers say the horses and burros have to be pared substantially. "If we don't receive relief, and soon, we'll be out of business," Lemoille, Nev., rancher Kenneth Jones"

^For example, the Irregular Times site describes a disagreement among Democratic Party regulars in upstate New York as a "range war". In this case the "unfenced territory" is an election district, and the hearts and minds of Democratic party regulars

^For example, the Mac Observer site characterises the conflict between IBM and the SCO Group as a "range war". In this case, the "unfenced territory" is the Unix/Linux marketplace, and the hearts and minds of technical, purchase influencing, IT people.
